Intron Definition
Introns have sequences that directs the splicing apparatus during RNA splicing, part of RNA processing:
| Introns begin and end with splice sites that conform to consensus sequences. |
| Introns always begin with a GU encompassed within a larger 5’ splice site consensus. |
| Introns always end with the branch point sequence, several pyrimidines and an AG. |
